Definitions
- the invention relates to an air outlet from a housing with a respective cylindrical housing inflow section and housing outflow section.
- the housing inflow section is provided with an inflow opening
- the housing outflow section with a larger diameter is provided with a plurality of outflow openings arranged in a uniform distribution over the edge region of a cover.
- a disc is mounted under the cover, through which, depending on its level, an annular overflow cross section from the housing inflow section to the housing outflow section can be blocked or released.
- Such an air outlet which is particularly suitable for installation in a cavity floor, is known, for example, from DE-A-34 17 002.
- This air pass has a cylindrical upper housing section, referred to as an air distribution head, under which a lower housing section, referred to as an air inlet pot, is rotatably arranged.
- a radial connection piece for connecting an air hose projects from the air inlet pot. This makes it possible to always bring the air hose in the floor cavity straight to the air outlet, regardless of the arrangement of feet.
- the known air outlet has a height-adjustable perforated disk, which serves to change the flow resistance of the air outlet, the change being brought about by rotating the cover.
- the perforated disc therefore only serves as a regulating disc, which causes a certain flow resistance.
- the height of the perforated disc above the supply air opening can be changed and can thus determine the size of an annular gap over which air can flow past the perforated disc.
- the height adjustment of the cover requires a partial disassembly and reassembly of the air outlet.
- a ventilation device is also already known from FR-A-939 973, in which a plate can be adjusted in height by means of a pin within the blow-out device.
- ring grooves are arranged at intervals in the pin, in which a ball can be locked in order to lock the plate at three different heights.
- the invention has for its object to improve an air outlet of the type described above so that it can be effectively closed and opened in a simple manner without disassembly and reassembly
- an air outlet of the generic type mentioned in the preamble of claim 1 is assumed, which according to the invention has the features specified in the characterizing part of the same.
- an overflow cross section from the housing inflow section to the housing outflow section can be shut off or released in a very simple manner, depending on the level thereof.
- the grid locking of the pin carrying the disk is used, the disk being held in the open position solely by the pressure of the helical spring and the disk being able to be moved into the closed position and being fixable by pressure against the action of the spring, although the spring is in this position of the disk has reached its maximum preload.
- an extremely simple and yet highly effective grid lock is used, as is known, for example, in ballpoint pens in which the ballpoint pen refill is axially displaceable between two end positions and can be alternately fixed in one or the other position by a simple push-button operation.
- a sleeve sits concentrically in the cover, through which the actuating pin can be inserted, with which the disk can be displaced and locked against the action of the cylinder spring both in the direction of the housing inflow section and also unlocked and displaceable in the direction of the housing outflow section.
- the air outlet essentially consists of a cylindrical housing inflow section 1 and a cylindrical housing outflow section 2, which are arranged coaxially to one another, the housing outflow section 2 being larger in diameter than the housing inflow section 1.
- the housing inflow section 1 is provided with an inflow opening, not shown, via which supply air can flow in from a floor cavity into the air outlet.
- the housing inflow section 1 is provided with a concentric sleeve 6 starting from a web 5, in which a pin 7 is guided, which carries a closure disk 8 at its end facing away from the sleeve 6, which is closed with the aid of a the pin 7 arranged coil spring 9 is displaceable from the extended position in FIG. 2 to the position shown in broken lines.
- a sleeve 10 is provided concentrically, through the opening of which an actuating pin (not shown) can be inserted, the shape of which is otherwise not subject to any requirements. If the actuating pin inserted through the sleeve 10 exerts pressure on a locking pin 11 projecting above the locking disk 8 and stored in the pin 7, the locking of the pin 9 is released and with the pin 9 the locking disk 8 is drawn from the drawn into the dot-dash line transferred position shown, whereby the overflow cross section between the housing inflow section 1 and the housing outflow section 2 is released.
- the closure disk 8 can be transferred just as easily from the dash-dotted to the extended position of FIG. 2, so that the overflow cross section between the housing inflow section 1 and the housing outflow section 2 is blocked and the air outlet thus remains inactive for as long as until a new displacement of the closure disk 8 is brought about.

Abstract
Description
Die Erfindung betrifft einen Luftauslaß aus einem Gehäuse mit einem jeweils zylinderförmigen Gehäuseeinströmabschnitt und Gehäuseausströmabschnitt. Der Gehäuseeinströmabschnitt ist mit einer Einströmöffnung versehen, wogegen der im Durchmesser größere Gehäuseausströmabschnitt mit mehreren über den Randbereich eines Deckels in gleichmäßiger Verteilung angeordneten Ausströmöffnungen versehen ist. Unter dem Deckel ist eine Scheibe gelagert, durch welche in Abhängigkeit von ihrem Niveau ein ringförmiger Überströmquerschnitt vom Gehäuseinströmabschnitt zum Gehäuseausströmabschnitt absperrbar bzw. freigebbar ist.The invention relates to an air outlet from a housing with a respective cylindrical housing inflow section and housing outflow section. The housing inflow section is provided with an inflow opening, whereas the housing outflow section with a larger diameter is provided with a plurality of outflow openings arranged in a uniform distribution over the edge region of a cover. A disc is mounted under the cover, through which, depending on its level, an annular overflow cross section from the housing inflow section to the housing outflow section can be blocked or released.
Ein derartiger, insbesondere für den Einbau in einen Hohlraumboden geeigneter Luftauslaß ist beispielsweise aus der DE-A-34 17 002 bekannt. Dieser Luftaulaß weist einen zylindrischen oberen, als Luftverteilkopf bezeichneten Gehäuseabschnitt auf, unter dem exzentrisch ein als Lufteinlaßtopf bezeichneter unterer Gehäuseabschnitt drehbar angeordnet ist. Von dem Lufteinlaßtopf steht ein radialer Anschlußstutzen zum Anschließen eines Luftschlauches ab. Damit ist es möglich, den Luftschlauch im Bodenhohlraum unabhängig von der Anordnung von Füßen stets geradlinig an den Luftauslaß heranzuführen.Such an air outlet, which is particularly suitable for installation in a cavity floor, is known, for example, from DE-A-34 17 002. This air pass has a cylindrical upper housing section, referred to as an air distribution head, under which a lower housing section, referred to as an air inlet pot, is rotatably arranged. A radial connection piece for connecting an air hose projects from the air inlet pot. This makes it possible to always bring the air hose in the floor cavity straight to the air outlet, regardless of the arrangement of feet.
Weiterhin weist der bekannte Luftauslaß eine höhenverstellbare Lochscheibe auf, die zur Veränderung des Strömungwiderstandes des Luftauslasses dient, wobei die Veränderung durch eine Drehung des Deckels herbeigeführt wird.Furthermore, the known air outlet has a height-adjustable perforated disk, which serves to change the flow resistance of the air outlet, the change being brought about by rotating the cover.
Bei dem bekannten Luftauslaß dient also die Lochscheibe lediglich als Regulierscheibe, womit ein bestimmter Strömungswiderstand hervorgerufen wird. Die Höhe der Lochscheibe über der Zuluftöffnung ist zwar veränderbar und kann dadurch die Größe eines Ringspaltes bestimmen, über welchen an der Lochscheibe Luft vorbeiströmen kann. Die Höhenverstellung des Deckels erfordert jedoch eine Teilde- und -remontage des Luftauslasses.In the known air outlet, the perforated disc therefore only serves as a regulating disc, which causes a certain flow resistance. The height of the perforated disc above the supply air opening can be changed and can thus determine the size of an annular gap over which air can flow past the perforated disc. However, the height adjustment of the cover requires a partial disassembly and reassembly of the air outlet.
In der Praxis ergibt sich häufig die Notwendigkeit, die Anzahl der gleichmäßig über beispielsweise eine Bodenfläche verteilten aktiven Luftauslässe je nach Nutzung des betreffenden Raumes zu verändern. Dazu werden bestimmte Luftauslässe verschlossen, wozu es erforderlich ist, die betreffenden Auslässe teilweise zu demontieren, um darin ein Verschlußstück einzubauen.In practice, there is often the need to change the number of active air outlets evenly distributed over, for example, a floor surface, depending on the use of the room in question. For this purpose, certain air outlets are closed, for which purpose it is necessary to partially dismantle the relevant outlets in order to install a closure piece therein.
Aus der FR-A-939 973 ist zwar auch bereits eine Lüftungsvorrichtung bekannt, bei der eine Platte über einen Zapfen innerhalb der Ausblasvorrichtung höhenverstellbar ist. Dazu sind im Zapfen Ringnuten in Abständen angeordnet, worin eine Kugel einrastbar ist, um die Platte in drei unterschiedlichen Höhen zu arretieren.A ventilation device is also already known from FR-A-939 973, in which a plate can be adjusted in height by means of a pin within the blow-out device. For this purpose, ring grooves are arranged at intervals in the pin, in which a ball can be locked in order to lock the plate at three different heights.
Der Erfindung liegt die Aufgabe zugrunde, einen Luftauslaß der eingangs beschriebenen Art so zu verbessern, daß er sich ohne De- und Remontage in einfacher Weise wirksam verschließen und öffnen laßt
Zur Lösung dieser Aufgabe wird von einem Luftauslaß der im Oberbegriff des Anspruchs 1 genannten gattungsgemäßen Art ausgegangen, welcher erfindungsgemäß die im kennzeichnenden Teil desselben angegebenen Merkmale aufweist.The invention has for its object to improve an air outlet of the type described above so that it can be effectively closed and opened in a simple manner without disassembly and reassembly
To solve this problem, an air outlet of the generic type mentioned in the preamble of claim 1 is assumed, which according to the invention has the features specified in the characterizing part of the same.
Bei dem erfindungsgemäßen Luftauslaß läßt sich durch die Verschlußscheibe in Abhängigkeit von deren Niveau ein Überströmquerschnitt vom Gehäuseeinströmabschnitt zum Gehäuseausströmabschnitt in einfachster Weise absperren bzw. freigeben. Dazu dient die Rasterverriegelung des die Scheibe tragenden Zapfens, wobei die Scheibe allein durch den Druck der Schraubenfeder in Offenstellung gehalten wird und die Scheibe durch einen Druck gegen die Wirkung der Feder in Schließstellung überführbar und darin fixierbar ist, obschon die Feder in dieser Position der Scheibe ihre maximale Vorspannung erreicht hat.In the case of the air outlet according to the invention, an overflow cross section from the housing inflow section to the housing outflow section can be shut off or released in a very simple manner, depending on the level thereof. For this purpose, the grid locking of the pin carrying the disk is used, the disk being held in the open position solely by the pressure of the helical spring and the disk being able to be moved into the closed position and being fixable by pressure against the action of the spring, although the spring is in this position of the disk has reached its maximum preload.
Beim erfindungsgemäßen Luftauslaß findet eine in ihrem Aufbau äußerst einfache und gleichwohl hochwirksame Rasterverriegelung Verwendung, wie sie beispielsweise bei Kugelschreibern bekannt ist, bei denen die Kugelschreibermine zwischen zwei Endpositionen axial verschiebbar gelagert und durch eine einfache Druckknopfbetätigung wechselweise in der einen oder anderen Position fixierbar ist.In the air outlet according to the invention, an extremely simple and yet highly effective grid lock is used, as is known, for example, in ballpoint pens in which the ballpoint pen refill is axially displaceable between two end positions and can be alternately fixed in one or the other position by a simple push-button operation.
Nach einer bevorzugten Ausgestaltung sitzt konzentrisch im Deckel eine Muffe, durch die der Betätigungsstift einführbar ist, mit dem die Scheibe gegen die Wirkung der Zylinderfeder sowohl in Richtung zum Gehäuseeinströmabschnitt verlagerbar und verriegelbar wie auch entriegelbar und in Richtung zum Gehäuseausströmabschnitt verlagerbar ist.According to a preferred embodiment, a sleeve sits concentrically in the cover, through which the actuating pin can be inserted, with which the disk can be displaced and locked against the action of the cylinder spring both in the direction of the housing inflow section and also unlocked and displaceable in the direction of the housing outflow section.
In der Zeichnung ist ein Ausführungsbeispiel eines erfindungsgemäßen Luftauslasses dargestellt. Es zeigen:
- Fig. 1
- den Luftauslaß im Grundriß
- Fig. 2
- den Luftauslaß in einem Schnitt nach der Linie II - II der Fig. 1.
- Fig. 1
- the air outlet in the floor plan
- Fig. 2
- the air outlet in a section along the line II - II of Fig. 1st
Der Luftauslaß besteht im wesentlichen aus einem zylinderförmigen Gehäuseeinströmabschnitt 1 und einem zylinderförmigen Gehäuseausströmabschnitt 2, die koaxial zueinander angeordnet sind, wobei der Gehäuseausströmabschnitt 2 gegenüber dem Gehäuseeinströmabschnitt 1 im Durchmesser größer ausgebildet ist.The air outlet essentially consists of a cylindrical housing inflow section 1 and a cylindrical housing outflow section 2, which are arranged coaxially to one another, the housing outflow section 2 being larger in diameter than the housing inflow section 1.
Der Gehäuseeinströmabschnitt 1 ist mit einer nicht dargestellten Einströmöffnung versehen, über die Zuluft aus einem Bodenhohlraum in den Luftauslaß einströmen kann.The housing inflow section 1 is provided with an inflow opening, not shown, via which supply air can flow in from a floor cavity into the air outlet.
Wie insbesondere Fig. 2 zeigt, ist der Gehäuseeinströmabschnitt 1 mit einer von einem Steg 5 ausgehenden konzentrischen Hülse 6 versehen, worin ein Zapfen 7 geführt ist, der an seinem von der Hülse 6 weg weisenden Ende eine Verschlußscheibe 8 trägt, die mit Hilfe einer um den Zapfen 7 angeordneten Schraubenfeder 9 aus der in Fig. 2 ausgezogenen Position in die strichpunktiert dargestellte Position verlagerbar ist.As shown in FIG. 2 in particular, the housing inflow section 1 is provided with a
Im Deckel des Gehäuseausströmabschnitts 2 ist konzentrisch eine Muffe 10 vorgesehen, durch deren Öffnung sich ein nicht dargestellter Betätigungsstift einführen läßt, an dessen Formgebung im übrigen keine Anforderungen gestellt werden. Wird über den durch die Muffe 10 eingeführten Betätigungsstift ein Druck auf einen über die Verschlußscheibe 8 vorstehenden und in dem Zapfen 7 gelagerten Rasterstift 11 ausgeübt, so wird die Verriegelung des Zapfens 9 aufgehoben und mit dem Zapfen 9 die Verschlußscheibe 8 aus der ausgezogenen in die strichpunktiert dargestellte Position überführt, wodurch der Überströmquerschnitt zwischen dem Gehäuseeinströmabschnitt 1 und dem Gehäuseausströmabschnitt 2 freigegeben wird. Durch eine erneute Druckbelastung des Rasterstiftes 11 läßt sich ebenso einfach die Verschlußscheibe 8 aus der strichpunktierten in die ausgezogene Position der Fig. 2 überführen, so daß der Überströmquerschnitt zwischen dem Gehäuseeinströmabschnitt 1 und dem Gehäuseausströmabschnitt 2 versperrt ist und damit der Luftauslaß so lange inaktiv bleibt, bis eine erneute Verlagerung der Verschlußscheibe 8 herbeigeführt wird.In the cover of the housing outflow section 2, a
